Abstract
The utility model relates to super 5-type four pairs of shielded twisted pairs, which comprise four groups of twisted pairs, polyester films, aluminum foil layers, copper woven meshes and PVC (polyvinyl chloride) protective jackets; each group of the twisted pair consists of two conducting wires, and each conducting wire comprises a core wire and a PE (poly ethylene) insulating layer coated on the core wire; the polyester films are coated on four groups of the twisted pairs; and the outer surfaces of the polyester films are sequentially provided with the aluminum foil layers, the copper woven meshes and the PVC protective jackets. The super 5-type four pairs of shielded twisted pairs provided by the utility model have the advantages of being quick in transmission speed, good in stability, low in error rate, good in shielding effectiveness and the like; and the super 5-type four pairs of shielded twisted pairs are provided with a tinned copper wire and a torn wire, so that the structure intensity of the twisted pairs can be enhanced, therefore, the super 5-type four pairs of shielded twisted pairs are hard to break.
Description
Technical field
The utility model relates to a kind of telecommunication cable, is specifically related to a kind of five types of 4 pairs of Shielded Twisted Pairs that surpass, and belongs to technical field of electric wires and cables.
Background technology
Along with increasing sharply of Internet user, people are also increasingly high to the performance requirement of the network operation.And the transmission speed of the double core communication line of prior art is often not fully up to expectations, and stability is poor, corrupted data is big, and shielding properties is poor, can not well be applicable to modern network communication; Simultaneously, the intensity of these double core communication lines is relatively poor, is easy to break outdoor setting up.And use the quality of copper-clad order wire heavier, be difficult for setting up.
Therefore, for solving the problems of the technologies described above, necessary a kind of structure improved five types of 4 pairs of Shielded Twisted Pairs that surpass that have are provided, to overcome said defective of the prior art.
The utility model content
For addressing the above problem, the purpose of the utility model is to provide that a kind of transmission speed is fast, advantages of good shielding performance and structural strength are big surpasses five types of 4 pairs of Shielded Twisted Pairs.
Be to realize above-mentioned purpose, the technical scheme that the utility model is taked is: a kind ofly surpass five types of 4 pairs of Shielded Twisted Pairs, it comprises four groups of twisted-pair feeders, polyester film, aluminium foil layer, copper mesh grid and PVC sheath; Wherein, said every group of twisted-pair feeder is made up of two leads, and each lead comprises a heart yearn and is coated on the PE insulating barrier on the heart yearn; Said polyester film is coated on four groups of twisted-pair feeders; Be provided with said aluminium foil layer, copper mesh grid and PVC sheath successively in said polyester film outer surface.
The five types of 4 pairs of Shielded Twisted Pairs that surpass of the utility model further are set to: between said polyester film and aluminium foil layer, be provided with a tinned wird; Between said aluminium foil layer and copper mesh grid, be provided with a tear line.
The five types of 4 pairs of Shielded Twisted Pairs that surpass of the utility model further are set to: said heart yearn is specially copper free wire.
Compared with prior art, the utlity model has following beneficial effect: to have transmission speed fast for the five types of 4 pairs of Shielded Twisted Pairs that surpass of the utility model, good stability, plurality of advantages such as low and advantages of good shielding performance of the error rate; Simultaneously, it is through being provided with a tinned wird and tear line, thereby has strengthened the structural strength of this twisted-pair feeder, makes it be difficult for breaking.
Description of drawings
Fig. 1 is the profile that surpasses five types of 4 pairs of Shielded Twisted Pairs of the utility model.
Embodiment
See also shown in the Figure of description 1, the utility model is a kind of five types of 4 pairs of Shielded Twisted Pairs that surpass, and it is made up of several parts such as four groups of twisted-pair feeders 1, polyester film 2, aluminium foil layer 3, copper mesh grid 4 and PVC sheaths 5.
Wherein, said twisted-pair feeder 1 is made up of two leads, and each lead comprises a heart yearn 11 and is coated on the PE insulating barrier 12 on the heart yearn 11, thereby two leads are not disturbed mutually.Said heart yearn 11 is specially copper free wire, thereby the transmission speed that makes this surpass five types of 4 pairs of Shielded Twisted Pairs is fast, good stability, and the error rate is low.
Said polyester film 2 is coated on four groups of twisted-pair feeders 1.Be provided with said aluminium foil layer 3, copper mesh grid 4 and PVC sheath 5 successively in said polyester film 2 outer surfaces.Wherein, through metallic aluminium foil layer 3, copper mesh grid 4 are set, thereby can effectively strengthen the shielding properties of this twisted-pair feeder.
Further, between said polyester film 2 and aluminium foil layer 3, be provided with a tinned wird 6; Between said aluminium foil layer 3 and copper mesh grid 4, be provided with a tear line 7.Through said tinned wird 6 and tear line 7 are set, thereby strengthened the structural strength of this twisted-pair feeder, made it be difficult for breaking.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection range of this creation.
